The Muliton Pattern is an initialization pattern in the sense defined in the notorious “Design Patterns” Book. Mulitons are like Singletons in that they use static methods to control access to a private constructor, but instead of maintaining a single copy of an object in an address space, a Multiton maintains a mapping from key values to objects. A number of uses are emerging for mulitons: (i) Multitons are useful when we want to use something like the Singleton pattern, but support multiple named instances of a system in an an address space and (ii) Multitons can be a useful representation of an object in a persistent store, such as a relational database.
